    MATLAB MATLAB Planetary Motion: Solving ODE45 & Plotting Orbits

    Ok that was a problem, I thought I did rewrite it and saved it but MATLAB kept using an older version for some reason. Figured that bit out now. I've tried to incorporate loops to calculate how each body affects the acceleration of the planet, in the case of 3 bodies there's a for loop with 2...

    MATLAB MATLAB Planetary Motion: Solving ODE45 & Plotting Orbits

    Ok now the next problem is that when i put the state vectors into a column as below: %Venus initial conditions VX0 = 1.08e11; %Position X VY0 = 0; %Position Y VVX0 = 0; %Velocity X VVY0 = 35000; %Velocity Y %Earth intial conditions EX0 = 1.496e11; %Position...

    MATLAB MATLAB Planetary Motion: Solving ODE45 & Plotting Orbits

    That does look familiar, thanks. I could do all this stuff on paper just not terribly well in matlab. I'll get there eventually.

    MATLAB MATLAB Planetary Motion: Solving ODE45 & Plotting Orbits

    Thanks for the reply. I think I can manage most of that however what I don't know how to do is to calculate the gravitational attraction between a planet at a position and a planet at another position. Would I use a similar function to the one I had before? the mind boggles. My vector...

    MATLAB MATLAB Planetary Motion: Solving ODE45 & Plotting Orbits

    Hello, Ive got a problem in MATLAB and have searched the internet a lot for help with this but nothing really addresses my issue specifically.\. I wish to use the ode45 solver to calculate and plot the orbits of all the planets in the solar system. I can manage just fine to get them to go...

    Engineering Change in career direction - biomedical science to Engineering

    Thanks for the replies. I intend to finish my degree so there's no problem there. I had considered biomedical engineering however wanted to keep my options open. Perhaps an electronic engineering degree and then later specialise in the masters years or something. Mainly the prpoblem I am...

    Engineering Change in career direction - biomedical science to Engineering

    I am currently in my honours year of a biomedical science degree in Australia, currently working on my thesis. Recently I've decided I would like to study Aerospace engineering or electronic engineering but have a few problems. Firstly I feel at 23 years of age I am somewhat behind and feel like...
